Solar Panel Car Battery Charger

Is it practical to use Solar Panels and batteries to run an HHO gas powered car?
I have just purchased an HHO generator which I intend to put on a Tercel. If I put Photovoltaic Panels on the roof of the car, and a deep cycle battery in the trunk with a plug-in charger, would it be realistically possible to make a sort of “Home made Hybrid?” Is there a limit to the ratio of HHo to gasoline that I can burn without damaging the valves, etcetera? Anyone out there trying to do something along these lines?
Then you wasted your money. HHO is just a scam that does nothing to help your fuel economy.
